What is the lateral surface area (the area not including the circular bases) of a cylinder whose base diameter is 4 cm and whose height is 6.5 cm? Round your answer to the nearest whole number.
-
The formula would be 2*pi*r*h, therefore the lateral surface area is 82. (81.68)
-
Circumference = pi* diameter= approximately 3.14 times 4 cm = 12 cm
multiply that circumference by the height= approximately 82 centimeters squared.
multiply that circumference by the height= approximately 82 centimeters squared.
-
2pi*2*6.5 = 82 cm^2
